I have to jump in. I was literally pained by this one creator who told me my characters/art was stiff needed improvement.
At first I accepted because my early drawings I felt were stiff. But I had updated some pages and panels I had posted & wondered if they saw that too.
It was responded with..."they are stiff from the first panel to the last. I needed more expressiveness, learn perspective. That my pages were static not dynamic."
I'm sharing this because it hurt and still does. Yeah, I'm aiming to do better. Learning over and over again. Maybe I don't catch on that fast. With no excuse, I've only come to know manga/anime for the last 5 years. I'm in my Golden years too, trying to teach this old "lady" new tricks. In my youth, I only knew comics like Casper, Archie, Dennis the Menace, Marvel & DC comics. I'm talkin' old days! Walt Disney studios was the animation to gawk at...for me, it's become Bones, and other anime/manga media.
Okay, I went back to check out their art...and come to know, they were unique, but I couldn't see why they'd target me? I mean, they seemed normal.
I don't want to "down" anybody. But it was one of the worst experiences. And I try not to criticize. Only if someone asks. If I do it, I sandwich it with something positive and the beginning and end. In the middle will be tutorial types of helps. That's as far as I go.
I hope I didn't harm the creator, but they just tore me up! Sorry for ranting. If need be, I can always delete this.
